European Pre-Muffler Catbypass Pipe

This European Pre-Muffler Catbypass Pipe is brought to you by FabSpeed for your Porsche. All 964 C2/C4/RS America products 1989-1994

+12HP & more torque.

High Quality T304 Stainless steel mirror polished showcar shine

O2 sensor bung so your 964 fuel injection system can automatically adjust mixture/idle/part throttle for maximum performance.

Just like Porsche factory German catbypass Euro-premuffler but without the $700.00 price.

LOOKS like a stock catalytic converter--best way to pass a visual exam inspection but the system straight ?see through? with an internal muffler inside.

Simple and easy bolt on installation.

Quieter and more durable than a mild steel straight pipe yet you can still roll a golf ball thru the Fabspeed pipe!

Catbypass & Fabspeed sport exhaust makes more horsepower than virtually any aftermarket exhaust system.

Best PROVEN performance value on the market.
Was: $468.75
Sale: $412.50



All parts come unpainted. Professional help required.
